GLUE-DISSOLVER AND RETAINER.

Specication'of Letters Patent.

Patented Mar. 1.1, 1913.

Application filed December 1 1911. Serial No. 663,327.

This invention rela-tes to improvements in' gluedissolving and retainingapparatus.

One object of the invention is to provide an apparatus of this characterhaving va nonsteam Contact dissolving and retaining mechanism wherebythe dissolved glue may ,be retained and kept warm until drawn from theapparatus.

A further object is to provide a glue dis`- solving apparatus having aglue dissolving pan adapted to be readily removed from the apparatuswhen. desired.`

With these and other objects in view the vinvention 'consists of certainnovel features of construction and the combination and ar rangement ofparts as will be more fully de# scribed and claimed.

In the accompanying drawings; `Figure 1 is a lcentral vertical sectionot my improved glue dissolving apparatus; Fig. 2 is a top plan viewthereof; with the lid or cover removed.

In the embodiment of the invention, I provide a main tank or casing lwhich may be provided with supporting legs 2 or supported in anysuitable. manner. In the tank 1 and spaced a suitable distance above thebottom thereof is a transversepartition 3 which forms in the lowerportion of the tank a water compartment 4 which is adapted to receivethe water formed by the condensation of the steam employed in dissolvingthe glue and by means of lwhich the dissolved glue is kept warm untildrawn from the apparatus. The partition 3 foi-ins the bottoni of adissolved glue compartment -5 and said partition or bottoni inclinesfrom one side of the tank toward the opposite side thereof in which sideat4 the lowest part ot' the partition or bottoin 8 is arranged a gluedischarging faucet- 6. A

The top of the dissolved glue compartment. is formed by a partition 7having therein a central opening the walls of which are bent upwardlyyto form an annular flange 9'. The partition plate 7 inclines toward theides of the tank 1 to which the edges of the partition are secured. The

y outer edges of t-he partitions 3 and 7 are preferably provided withdepending annula'r flanges secured to the inner surface of a fluid tightjoint or connection between these parts.

ofthe tank. and supported upon the partition 7 is aglue dissolving panlO'of less diameter than the inner diameter of the tank vand having itsside walls inclined inwardly and its bottom 11 vinclined from the outeredges thereof downwardly toward a central opening 12, the walls ofwhichl are bent downwardly to form an annular flange-.13 which isadapted to llt closely Within .the flange 9 whereby the pan lO'issupported and held in a concentric position in the tank.

steam into the compartment 5 or into the pan is herein shownin the formof interlocking flanges on the bottom of the glue with the partition andpan, it is obvious dthat they are not necessarily so but may be securedthereto in any suitable manner.

thereon an annular downwardly' extending vdrip dellecting ring or flange13 which is spaced a suitable distance from the flange 13 and engages oris disposed adjacent to the outer side o'f the flange 9 on the partition7, said drip dellecting flange lireventing any drip from passing betweenthe flanges 9 and 13 and into the melted glue compartment 5. By thusarranging the ring or 'flange 13 it will be. seen that any steamcondensing on the sides oi the glue dissolving pan 10 and running downthe sides andaround the bot-` toni thereof will be detlected'by theflange 13 and caused to flow down'over the partia suitable mannerhereinafter described. The arrangement of the partition 7 and bottom ofpan l0 facilitates the passage of the water of condensationto the meanstherefor hereinafterto be described, and the drip flange 13 prevents4all danger ofthe water entering the compartment.

Removably arranged in the upper portion Means for preventing theentrance 'ofpan 10 and the upper face of the partition 7. e lVhile theseflanges are shown as integral In addition to the flange 13 the bottomofl the glue dissolving pani() has-also formed tion 7 from which thesame is carried off in from the edges of the opening 8 downwardly l ithe sides of the tank 'in any manner lo yform Theopening 12 in thebottom of the pan is covered by a screen 14 through which the dissolvedglue drips into the dissolved glue compartment arranged below thepartition 7. On theupper edge of the glue dissolving pan is arranged anoutwardly projecting bead or flange 100 which when the pan is' in place,engages the upper edge of a right angular-ly formed annular gutter ortrough secured to the inner side of the tank adjacent to its upper endas shown. The gutter or trough 15 forms a closure between the upperportion' of the tank and the outer. sides of the pan for a purposehereinafter described. The pan 10 is provided with suitable handles 1Gwhereby the same may be readily lifted from the upper 4portitn of thetank. The upper open end of the pan 10 and the upper end of the tank areclosed by a conical shaped cover 17 having on its under side adjacenttoits outer edge a depending 'flange 18 which fits into and engages theupper end of the tank as shown. The space between the partition 7 andthe trough or gutter and surrounding the glue dissolving pan 10 forms a.steam chamber 19 with onev side of which is connected a steam inlet pipe20 and with the opposite side of which, near the upper end thereof, isconnected Aa steam discharging or pressure relieving pipe 21. 0n theinner side of the casing 1 over the end of the steam inlet pipe 20 isarranged a deilecting plate or hood 20 against which the steam strikeson entering the steam chamber 19 and by which the steam is deflected andcaused to circulate uniformly around and through the chamber.

rlhe partition 7 which forms the top of the dissolved glue compartmentand the bottom of the steam chamber is slightly lower at one side `andwith said lower portion of the partition is connected the upper end ofthe condensed steam conducting or drain pipe 22 which extends downwardlythrough the dissolved glue compartment andthe partition S to a point.near the hottom ytxt the water compartment fl whereby the steamcondensing in the. chamber 19 is conducted toV the water compartment.Also discharging into the water compartment 4 is a drain' or condensedsteam conducting pipe 23 which also passes upwardly through thgcompartment and partition 7 and has its upper,end connected with thegutter or trough 15 whereby any water of condensation accumulating onthe inner side of the lid or cover 17 and dripping therefrom into thegutter is drained from the latter and conducted'to the water compartment4. The water of condensation thus conducted to the compartment 4 servesto keep the dissolved glue'warm in the compartmentr.

The water compartment 4 is provided in,

one side with an overflow pipe 24, near the upper end thereof orimmediately below the partition 3 as shown. The water compartment Il isalso provided in one side with a draw oil' faucet 25 by means of whichthe water may be removed from said compart` ment when desired.

By thus constructing and arranging the various parts of the apparatusthe steam employed for dissolving or melting vthe glue in the pan 10cannot reach or come in con;- tact with the glue either while beingdissolved or after the saine has entered the dissolved gluecompartment.' V'By thus dissolving the glue without permitting the steamto come into contact therewith the quality of the glue is greatlyimproved. By thus constructing and arranging the various parts of theapparatus it will be, seen that both the dissolving compartment or panWand the retaining compartment are com-4 bined 'ordisposed in one tankthus providing a compact and eflicient apparatus for the purposedescribed.

Attention is invited to the peculiar and advantageous arrangement of theinterior construction of the apparatus and per cularly to the manner in,which the remo-mille dissolving pan issuppcrtcd by means of thepartition 7 which serves thc two-fold pose ofa cover for the dissolvedgi' partment and a support for the di' .f pan which, when enga-ged with.',he part 7 forms a steam tight connection .hetvecn the pan and thedissolved glue colinpartment at the same time permitting the pan to hereadily removed from the apparatus when desired. Further attention isinvited to the arrangement ofthe warming feature of the apparatuswherein the melted .eine .in the compartment 5 1s kept warm by tue fromthe water of condensation dripping into the water compartment ll and bysuch part of the steam as may pass fronr the steam chamber 19v throughthe drain 22 to the water compartment.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing :from the principle orsacrificing any of the advan tages of the invention as claimed.
